About this application

We wrote the original version of Worldmap for
Sysquake to experiment with
different
map projections. Vector maps are loaded from
Shapefiles;
data themselves come from Natural Earth
@ naturalearthdata.com.
We saved the data to an SQD file (Sysquake data file which retains the state of
an interactive Sysquake application) to avoid the dependency on a separate file.
Then we converted it to JavaScript with our tools to embed it in this HTML page.

Worldmap, like other Web interactive applications built with Sysquake,
shares the JavaScript technology Calerga has developed for
Sysquake Mobile.
